I thought #heightToDisplayInList:  looked promising, but overriding it to
force a particular value like this...
```
ButtonPresenter subclass: MyButtonPresenter
    ...etc

MyButtonPresenter >>  heightToDisplayInList: aList
    ^200
```

then doing...
```
cls := 'Files'  asPackage  classes anyOne.
mbp := MyButtonPresenter new icon:  cls  systemIcon;  label:  cls  name.

lp := ListPresenter  new
  displayBlock:  [  :x  |  x  buildWithSpec  ];
  items: {mbp. mbp}.
lp openWithSpec.
```

didn't change the row height.
